X-Git-Tag: v6.1-rc5~2218^2~37^2~34
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=411943344599d1a3340b4f720157cd24f4768c92;p=platform%2Fkernel%2Flinux-starfive.git

habanalabs: add more info ioctls support during reset

Some info ioctls can be served even if the device is disabled or
in reset. Hence, we enable more info ioctls during reset, as these
ioctls do not require any H/W nor F/W communication.
